Description

Technical Field

[0001] This utility model relates to the field of cable installation device technology, specifically to a novel cable clamp and installation assembly. Background Technology

[0002] Insulation-piercing branch clamps are often used during the connection of conductive cables to electrically connect the main cable to one end of the branch conductor. For example, the conductive cable branch clamp disclosed in our authorized publication number CN219917612U uses fasteners to bring the first and second clamping bodies close together to clamp the cable. To better clamp cables of different thicknesses, the second clamping body can usually swing back and forth relative to the first clamping body. However, after swinging forward or backward, the contact area between the nut at the fastener or the washer below it and the second clamping body decreases, thus reducing the stability of the second clamping body, which requires improvement. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] The first aspect of this application discloses a novel cable clamp, including a fastener, a first clamp body, and a second clamp body. The fastener includes a threaded component and a limiting component that is threadedly engaged with the threaded component. The first clamp body and the second clamp body are disposed vertically opposite each other on the threaded component, and the tail end of the threaded component passes through a through hole formed in the upper second clamp body and connects to the limiting component. When the limiting component moves downward, it drives the second clamp body to approach the first clamp body to clamp the cable between the two. The through hole provides space for the second clamp body to swing back and forth relative to the first clamp body. The application also includes a pad. The tail end of the threaded component passes through a second through hole formed in the pad, and the pad is located between the limiting component and the second clamp body. The second through hole provides space for the pad to swing back and forth relative to the first clamp body. By swinging the pad, the contact area between its bottom and the second clamp body is increased.

[0005] When in use, if the second clamping body swings backward relative to the first clamping body, the angle between the second clamping body and the first clamping body becomes larger, making it easier to clamp thicker cables. Then, the pad is also swung backward to increase the contact area between the pad and the second clamping body. Finally, the pad is pressed down by the limiting member, which simultaneously drives the second clamping body closer to the first clamping body to clamp the cable in the middle. With this structure, the contact area between the pad and the second clamping body is large, and the limiting member can better suppress the second clamping body, thus improving the stability of clamping.

[0006] Furthermore, the pad is slidably connected in a guide groove provided on the top surface of the second clamp, so as to guide the back and forth movement of the pad and improve the stability of the pad movement.

[0007] Furthermore, the bottom surface of the pad and the top surface of the second clamp below it are both arc-shaped to fit together, and the top surface of the pad is flat, which helps to increase the contact area between the two.

[0008] Furthermore, elastic insulators are respectively provided on the faces of the first clamp and the second clamp, and clamping positions are provided on the elastic insulators. An elastic material blocking block is provided at the end of the clamping position. The blocking block can further restrict the cable from detaching and improve the stability of the cable installation.

[0009] Furthermore, a limiting post is provided on the longitudinally protruding surface of the first clamping body facing the second clamping body. A through hole three is formed along the axial direction of the limiting post on the limiting post and the corresponding first clamping body for the threaded part to pass through. The end of the limiting post extends into the through hole one and cooperates with the through hole one to restrict the circumferential rotation of the second clamping body relative to the first clamping body. By limiting the rotation of the second clamping body by the limiting post, the stability of clamping is improved.

[0010] Furthermore, the limiting post is rectangular or multi-faceted, and the through-hole section into which the limiting post extends has the same shape as the limiting post.

[0011] Furthermore, the through hole three formed through the first clamping body is connected to the threaded component through the threaded connection. The threaded component and the through hole one on the second clamping body slide in the longitudinal direction. The longitudinal sliding connection of the second clamping body facilitates the expansion of the distance between it and the first clamping body, making it easier to insert thicker cables. The threaded fixing structure between the first clamping body and the threaded component facilitates the quick formation of clamping action.

[0012] Furthermore, the limiting member includes a body and wings. The body is threadedly connected to the threaded member, and the wings are relatively protruding on both sides of the body. The wings are added to facilitate force application, making it easier to use, such as by directly applying force to the wings with your fingers to rotate the limiting member.

[0013] Furthermore, a washer is fitted on the threaded part between the limiting member and the pad block. The washer helps to limit the rotation of the limiting member and improve the stability of clamping.

[0014] The second aspect of this application discloses an installation component, including the aforementioned wire clamp and mounting parts. The mounting parts include a threaded rod, an insulating first clamp, a second clamp, a handle, and an end cap. The first clamp and the second clamp are disposed opposite each other at the tail end of the handle. The second clamp is slidably connected to the handle in its axial direction. The second clamp is threadedly engaged with the tail end of the threaded rod, and the threaded rod is rotatably connected in the handle cavity. The end cap is rotatably connected to the head end of the handle and is connected to the head end of the threaded rod. Under the drive of the threaded rod, the second clamp moves toward the first clamp by rotating the end cap to cooperate in clamping the protruding end at the bottom surface of the first clamp body. The insulating first clamp, the second clamp, the handle, and the end cap can improve the installability.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The pad in this clamp can swing with the second clamp to maintain a larger contact area, which helps to improve the clamping stability of the first and second clamps.

[0017] 2. The first clamp, second clamp, handle, end cap, etc. in this installation assembly are all made of insulating material, which helps to improve the safety of installation. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 , Figure 2 As shown, the new type of wire clamp includes a fastener, a first clamping body 1, and a second clamping body 2. The fastener includes a threaded part 12 and a limiting part 3 that is threadedly engaged with the threaded part 12. For the threaded part, such as a common bolt, the limiting part is such as a nut that mates with the bolt, and the nut is threadedly engaged with the bolt.

[0030] The first clamping body 1 and the second clamping body 2 are positioned vertically opposite each other on the threaded component 12. For example, a through hole 3 11 is formed longitudinally through the first clamping body 1, and a through hole 10 is formed longitudinally through the second clamping body 2. The second clamping body 2 is positioned above the first clamping body 1, and the through holes 3 11 and 10 correspond vertically so that the tail end of the threaded component 12 passes through both through holes 3 11 and 10. The head end of the threaded component 12 is located at the first clamping body 1. Preferably, the through hole 3 11 at the first clamping body 1 is threadedly engaged with the threaded component 12 to fix them as a single unit. The through hole 10 at the second clamping body 2 is slidably engaged with the threaded component 12 longitudinally. A limiting member 3 is threadedly engaged at the tail end of the threaded component 12, which protrudes outward from the top surface of the second clamping body 2. During use, if the limiting member is screwed downwards, it presses down on the second clamping body, bringing it closer to the first clamping body and thus clamping the cable between them. Regarding the specific structure of the first and second clamps, corresponding models can be selected from the market according to the requirements, preferably the configuration of the first and second clamps disclosed in the authorization announcement number CN219917612U.

[0031] In this example, through hole 10 provides space for the second clamp 2 to swing back and forth relative to the first clamp 1, such as... Figure 2 As shown, the length of the through hole 10 in the front-to-back direction is greater than the diameter of the threaded part 12. The second clamping body 2 is tilted forward relative to the first clamping body 1 (e.g., Figure 2 (As shown by the arrow), then the second clamp 2 and the left side of the first clamp 1 ( Figure 2 In the state shown, the distance between the two clamps is shortened to accommodate thinner cables. Similarly, if the second clamp is swung back relative to the first clamp 1, the distance between the second clamp 2 and the left side of the first clamp 1 increases to accommodate thicker cables.

[0032] To improve clamping stability, a pad 7 is added in this example. The pad 7 has a through-hole 8 formed throughout it. The tail end of the threaded part 12 passes through the through-hole 8 formed in the pad 7. The pad 7 is positioned between the limiting member 3 and the second clamping body 2. In this example, the through-hole 8 provides space for the pad 7 to swing back and forth relative to the first clamping body 1. Similarly, if the length of the through-hole 8 in the front-back direction is greater than the diameter of the threaded part 12, then when the second clamping body swings forward relative to the first clamping body, if the pad remains in its original state, the contact area between the pad and the second clamping body will decrease. At this time, the pad can also be swung forward relative to the first clamping body, thus increasing the contact area between the bottom of the pad and the top surface of the second clamping body. The limiting member presses down against the pad, increasing the contact area between the clamp and the second clamping body, which helps improve clamping stability. To limit the reversal of the limiting member, a shim 9 can also be added. For example, a shim 9 can be fitted onto the threaded part 12 between the limiting member 3 and the pad 7. The limiting member presses down on the shim, and the shim abuts against the pad.

[0033] To facilitate the fitting of the pad and the second clamp, it can also be as follows: Figure 2 As shown, the bottom of the pad 7 and the top surface of the corresponding second clamp 2 are both formed into an arc shape. After swinging, the pad 7 can also fit against the top surface of the second clamp 2, maintaining a large contact area.

[0034] To improve the stability of the pad's movement, a guide groove 14 can be formed on the top surface of the second clamp 2 along the moving direction of the pad 7. The pad 7 is placed in the guide groove 14, and the guide groove 14 and the pad 7 are guided by their back-and-forth movement. The bottom wall of the guide groove corresponding to the pad's movement range is arc-shaped to facilitate fitting. In addition, it is preferable that the top surface of the pad 7 is flat, which can maintain a large contact area with the limiting member or gasket, thereby improving stability.

[0035] To restrict the circumferential rotation of the second clamping body relative to the first clamping body, in this example, a limiting post 13 is formed longitudinally outward on the surface of the first clamping body 1 facing the second clamping body 2. A through hole 11 for the threaded component 12 to pass through is formed along the axial direction of the limiting post 13 on both the limiting post 13 and the corresponding first clamping body 1. The end of the limiting post 13 extends into the through hole 10 and cooperates with the through hole 10 to restrict the circumferential rotation of the second clamping body 2 relative to the first clamping body 1. For the limiting post, such as a common rectangular column shape, the through hole 10 into which the limiting post 13 extends has the same shape as the limiting post. If it is also rectangular, the limiting post and the through hole 10 cooperate to restrict the circumferential rotation of the second clamping body, but will not significantly restrict the back-and-forth swing of the second clamping body relative to the first clamping body. Figure 2 As shown.

[0036] As described in the authorization announcement number CN219917612U, in this example, elastic insulators 4 are also installed on the faces of the first clamp 1 and the second clamp 2 respectively. An arc-shaped groove is formed on the elastic insulator, namely the clamping position 5. A blocking block 6 is formed by protruding from the elastic insulator at the end of the clamping position 5. The blocking block is like a common sheet. The blocking block can further restrict the cable from falling off and improve the stability of the cable installation.

[0037] The limiting components can be selected from the market according to requirements, preferably such as... Figure 3 The configuration shown, such as the limiting member 3, includes a cylindrical body 31 and fins 32. The body 31 is fitted onto the threaded member 12 and is threadedly engaged with the threaded member. The fins 32 are formed to protrude outward on both sides of the body 31. The specific configuration of the fins can be selected according to the requirements. Commonly, they are arc-shaped, but L-shaped, straight, or other configurations can also be used. Adding fins makes it easier to apply force and use the limiting member by directly applying force to the fins with your fingers. This makes it more convenient to use.

[0038] For the materials of the first and second clamps, if insulating materials are used, insulating and flame-retardant materials can be selected.

[0039] Example 2

[0040] like Figure 4 , Figure 5 , Figure 6 As shown, this mounting assembly includes the wire clamp and mounting component 15 described in Embodiment 1. The mounting component 15 includes a threaded rod 151, a first clamping block 153, a second clamping block 152, a handle 150, and an end cap 154. The first clamping block 153, the second clamping block 152, the handle 150, and the end cap 154 ​​can be directly molded from an insulating material, preferably a material resistant to 10KV, or they can be wrapped with an insulating layer to provide insulation properties. The first clamping block 153 and the second clamping block 152 are mounted opposite each other at the tail end of the handle 150, with the first clamping block 153 fixed to the tail end of the handle 150. The second clamping block 152 is slidably connected to the handle 150 in its axial direction. If the bottom of the second clamping block has a sliding rod, the sliding rod is slidably connected to the groove formed at the end of the handle. The sliding rod at the bottom of the second clamping block 152 is threadedly engaged with the tail end of the threaded rod 151, and the threaded rod 151 is rotatably connected in the cavity of the handle 150. The end cap 154 ​​is rotatably connected to the head end of the handle 150 and is connected to the head end of the threaded rod 151. Under the drive of the threaded rod, the second clamping block 152 moves toward the first clamping block 153 by rotating the end cap to cooperate in clamping the protruding end 16 on the bottom surface of the first clamping body 1. The protruding end is preferably in the shape of a multi-ridged prism to facilitate the cooperation and clamping of the first clamping block and the second clamping block. After clamping, it is convenient to turn the limiting member, making installation more convenient.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
